Bobby, Is the logger recording rpm , battery voltage and any other functions you have configured into the system?
If so, you may want to check the O2 sensor wiring at the DFI box.
Also, these units are very sensitive to proper grounding. With ignition on, activate your Analyzer while hooked up to your laptop and see if the O2 sensor lights on the bottom left of the screen turn green after 15-20 seconds or so. If they do, that indicates the sensors are heated up and functional. If not, you are not getting power to the sensor(s).

I have the old Accel Calmap unit and have the DFI box as a stand alone only used for the O2 readings.( got the car this way). I believe 17.99 is the system default reading when the O2's are not functioning properly.
I am no expert on this stuff.....but I struggled thru the learning process and finally got it to work.
I have a phone number of a service guy in Alabama that is an Accel dealer. He was a big help in getting mine functional. Let me know if you need it and I'll dig it up.
Hope this helps.
John
